The King has apologised to the Army for making a visit at the last moment but said that he had wanted to come as soon as he had been “allowed out of my cage”.
Charles made his comments during a visit to the 3 Royal School of Military Engineering (3RSME) at Gibraltar Barracks, Minley, Surrey.
As he was led into the officers’ mess by Lieutenant Colonel Robert Grant, commanding officer of 3RSME, the King said to him: “I do apologise for taking you by surprise, when this opportunity appeared and I had been allowed out of my cage, I wanted to come to have a look.”
Lt Col Grant told the PA news agency: “We only had six days to pull this together but the only answer from us was ‘yes’.
“There was a palpable sense of excitement as you saw the units spark into life for the visit.”
He shared a joke with Natalie Newman, the wife of Corporal Joseph Newman, when she told him that they had three children.
Charles told her: “Nothing a strong drink won’t help.”
When Cpl Newman told him that his role was as an electrician, he said to Mrs Newman: “Terribly helpful to have an electrician around.”
She replied jokingly: “Well, you say that!”
Speaking afterwards, Mrs Newman, 34, from Poole, Dorset, said: “It was amazing, nerve-wracking, but amazing.
“I just said how many children I had, I said I had three children, and he said ‘It was nothing a strong drink won’t help’.
Cpl Newman, 32, said: “He is a really lovely person, he liked to engage with you, it wasn’t a fleeting chat, it was an in-depth conversation.”
The King also met officers from the 8 Engineer Brigade HQ, which provides engineering support to military operations and, before he left, Charles signed the regiment’s visitors’ book and was presented with gifts of flowers and Royal Engineer china mugs from the children of some of the barracks’ serving soldiers.
He also took the chance to meet families and staff members who waited outside to see him leave and the King told them: “Aren’t you all meant to be having lunch?”
The King was then presented with a portrait of himself drawn by six-year-old Louie Bacon, son of Warrant Officer 2 Mark Bacon.
Louie said it was good to meet the King and he was very excited.
Mother Kim Lewis, of Fleet, said: “It was really exciting, a once-in-a-lifetime chance, definitely worth half a day off.”
The 3RSME was formed in September 1939 as the Combat Engineer Centre of Excellence.
All Royal Engineer soldiers and officers pass through 3 RSME to receive combat engineer initial trade training.
The school is responsible for providing command courses at the junior and senior level, as well as combat engineer courses, teaching skills such as bridging, demolitions and water supply.
